<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We just started testing 64 bit MGO 2.2 on windows 2008R2. When we load tested our site with 10 simultaneous users, the Mapguide service stops responding and we had to restart the service.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I thought MGO2.2 is fixed to handle around 500 connections at the same time compared to 64 connections in MGO2.1.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Please throw some ideas for the performance issue.<o:p></o:p></p>
